Best firewall app for my limited needs? - eviltoast

Hey all,

I want a firewall app for just basically to enforce restrictions on outgoing communication based on service or app. It is mostly to block data harvesting. For reference, if anyone remembers there was one for iPhone called Firewall IP and it was just perfection. That was back when we could jailbreak.

Anyway, so that’s all I need. Free is best, of course, but I would pay a bit if it is an exceptionally good product. No problem paying for quality. But I will have no interest in anything that’s subscription based, nor anything that I need some kind of backend “approval” or login in order to install and use it. In other words, I want to know that if in a hundred years I happen to have a working phone from today, and the apk file, then I can install it. Obviously that’s reductoi ad absurdum but you get my point.

Thanks for any recommendations. P.S. I’m not rooted, if that matters. Although I am still interested in possibly getting a replacement ROM for my device.
